About Us
At Lemurian Labs, we're reimagining the foundations of computing to make AI accessible to everyone. Our mission is to remove the limits of scale, hardware, and cost that hold back innovation, so the people solving humanity's hardest problems can move faster.
We're building a new kind of software stack: a hardware-agnostic platform that makes every system — from a laptop to a supercomputer — feel like one seamless engine. Developers can write once, run anywhere, and get state-of-the-art performance across any chip, any cloud, at any scale. It's a complete rethink of how software and hardware interact — designed for the era beyond Moore's Law.
We're not looking for the comfortable or the conventional; we're looking for the bold. The engineers who crave frontier problems, who want to bend the limits of what's possible, who see infrastructure not as a constraint but as a canvas. If you want to build the foundation for the next era of AI and change what humanity can achieve in the process, join us.
About the Role
As the founding member of our Developer Experience (DevX) team, you will be instrumental in shaping how engineers interact with our compiler infrastructure. You'll build the tools that give developers deep visibility into system performance—from profiling and debugging capabilities to hardware introspection interfaces. Your work will bridge the gap between our core compiler technology and the engineers who use it, transforming complex system data into actionable insights.
This role sits at the intersection of systems programming and developer tooling. You'll work closely with our compiler engineers to surface server-side telemetry through intuitive client-side interfaces, ultimately creating a best-in-class development experience for our users.
What You'll Do
- Design and build developer tools for profiling, debugging, and performance introspection across our compiler stack.
- Create client-side tooling that transforms server-side compiler telemetry into clear, actionable information for engineers.
- Develop interfaces that expose hardware performance metrics, and interrupt data in meaningful ways.
- Build GPU debugging capabilities and visualization tools to help engineers understand execution on heterogeneous hardware.
- Define formats and protocols for debug information exchange, working with standard debugger formats (DWARF, JTAG) and object file formats (ELF, COFF).
- Collaborate with internal engineering teams to understand their needs and iterate on tooling, with a path toward external customer-facing tools.
Essential Skills and Experience:
- 3+ years of professional experience in systems-level software development.
